1 nEvoLvme DOOR STRUCTURE,

Specification of Flatter-s Patent.

Patented March 5, 1907.

Application filed October 21,1905. Serial 110,283,864,

To all whom. if many concern:

Be it known that I, BURNS HULL UHRICH, of Atchison, in the county of Atchison and State of Kansas, have invented certain new and useful Improvements in Revolving Door cation.

This ll'iVQIltlOnTGlfitQS to certain new and useful mprovements in revolving door structures such as'are now quite commonly used, the objects of my invention being to provide adoor of good appearance and of simple construction, with means for giving a wider opening when not in use and for doing away with unsightly slots in the ceiling and any projections of the wings beyond the casing when folded. I.

With these objects in view my invention consists in the storm-door structure, as will be now hereinafter more particularly dcscribed and then definitely set forth by the claims at the end hereof.

- In the drawings accompanying and forming part of this application, and which represent the preferable though not necessary embodimentof my invention, Figure 1 is a horizontal section of a revolving-door structure,

showing iny-"invention with the curved wings shown in full lines in position for use and in dotted lines in the positions they occupy when folded. Fig. 2 is a view,'partly in side elevation and partly in section, of the same, except that this view of" course shows the ceiling and the rotary support, &c. Fig.3 shows the upper pivot'located at the outer edges of two of tltewing's, together with the socket for the same. Fig. 1 shows in sectional view the actuating mechanism for the pivots at the outer ends of two of the wings. Fig. 5 shows a series of details comprising the lower pivot and its socket, the pivot being operated by the means shown in Fig. 1. Fig. 6 is a vertical section through the entire structures shown-in Figs. 3, 4, and 5. Fig. 7

. is a front elevation of the face-plate and operating-disk. Fig. 8 shows a face view of one of the sockets of the outer pivots. Fig. 9 is a section showing the hinge by which the wings are connected together. Fig. 10 is top plan view of the ball-bearing support for the rotating wings. Fig. 11 is a sectional view of said ball-bearing support. Fi 12 is a detail showing the relation of the re olving part of the rotating hanger and the wings. Fig. 13

is a rear view of one of the plates fastened to the Wings carrying part of the locking mechanism. Fig. 14 is ahorizontal section of art of the wings andpart of the locking mec anusin. Fig. 15 is a vertical section of the structure shown in Fig. 1 1. Fig. 16 is an elevation of the facelate and operating-disk by which the main ock is operated. Fig. 17-is a vertical section of a detail showing the main locking mechanism. Fig. 18 is a sectional detail looking at the rear of Fig. ,17. Fig. 19 is a horizontal section, and Fig. 20 is an elevation, of the socket for the lowerpivot. Fig. 21 is a sectional detail of the lower pivot and its socket. Figs. 22, 23, and 24'are details showing the drop-arm and its parts for locking the wings when in position. Figs. 25, 26, 27, and 28 are detail views of mechanism for locking the two sections together.

Referring now to the details of the drawings by numerals, and particularly to Fig. 1, it will be observed that the revolving part of the door consists of four wings 1, 2, 3, and 4. The wings 2 and 4 are formed with wide overlapping stiles, which are locked to each other and to the center bearing by means which will be hereinafter described. The wings 1 and 3 are hinged, respectively, to the wings 2 and 4 by means of hinges of the form shown in Fig. 9, and these wings I and 3 may be folded against the wings 2 and 4, as illustrated in dotted lines in Fig. 1, or they may be opened to the full position. (Shown in full lines in Fig. 1.) When they are in the osition shown in full lines in said Fig. 1, t icy are held in said position by means of drop-arms 5. These drop-arms 5 are pivotally supported at one end in sockets 30 and coact with catches 6 upon the other wing, as illustrated in Fig. 2. In Figs. 22, 23, and 24 these drop-arms and their parts are clearly shown. As there illustrated, the drop-arms are pivoted to the members 30, while their opposite ends are bent to enter thecatches 6,

which contain a latch 31, normally held in place by a spring 32 and cover-plate 33. To release the latch so that thedrop-arm will fall out of the catches 6, it is only necessary to slightly withdraw the latch 31 by pulling on the knob at its end, when the drop-arm will be released and may drop down against the side of the wing in a manner easily linden stood. When these drop-arms are released and in their downward position, the wings 1 and 3 may be moved on their hinges, so as to fold against the wings 2 and 4, and it may now be observed that these wings instead of being formed of straight orplane surfaces are curved, so that when they are folded in position they will not only fit close to each other, but will also be close to the interior wall of the circular casing, as clearly shown in dotted lines in Fig. 1. I deem this of great iniversely of the door structure.

portance.

' In order to properly support the wings 1, 2, 3, and 4 and allow their proper rotation, I employ a hanger shown particularly in Figs. 2, 10, and 11. This hanger or rotating sup port is markedll in Fig. 11, and its shape is more particularly shown in Fig. 14. The upper end of this hanger or rotating support- 11 is provided with a' threaded shaft end on which is screwed a steel cone 14 of the ballbearing, a steel cup-plate 15 being bolted to the steel channel-iron 16, running trans- The cone is prevented from turning independently of the shaft end by means of a lock-nut 17, the whole forming an antifriction bearing-support requiring no oiling or other attention. The hanger or rotating support 11 is of-the peculiar shape shown in-Figs. 11 and 141and has two offset portions, leaving spaces for the o crating mechanisms hereinafter describe The wings 2 and 4 when they are in the position shown in full lines in Fig. 1 have their stiles fitting on opposite sides of the offset hanger or rotating support 11, as shown in Figs. 12 and 14. The wings, as shown in these figures, are cut away and faced with recessed plates 22, screwed to the wings, as clearly shown in Fig. 1 4. jTh'eseplates 22 are so formed as to leave a space within.

which works part of the locking mechanism.

The mechanismsfor locking the wings 2 and 4 to the hanger or rotating support 11 comprise the following elements: A rock shaft 20 with crank-arm 19 and locking-arm 13 is slipped through slot 18 in one of the before. said plate is secured face-plates 22 in position, and to rock this shaft 20 I employ a rod 21 and other connections-which will be described. The hanger or rotating support 11 is provided with recesses 12, and when the i wing 2 is moved up against this hanger or support 11 the lock-arm 13 projects through one of the slots .12. The operating mechanism may then' be moved-so t full linesinFig. 1 1-)'-'to;the vertical locking position; (Shown; in dotted lines in said figure.)

.ment with the shaft or rotating support 11 is secured a floor-socket. (Shown in Fig. 21 and also in dotted lines in Fig. 2.)- The lower pivot 29, which coacts with this socket,

curely together. on theshaft-20 and the rod 44 is connected with. wrist-pin 47 on thiscrank. Rod 44 is operated by the same mechanism as shown at the rod 2-1 rocks' shaft. 20 and moves the-:lockhig-arm 13 from. the horizontalunlocked position (shown in works through a socket 29, secured to the lower end of the wing 2, so that it may be projected through the socket 29 into the floor-socket in order that the wings may have a bottom pivot on which to turn. In order to simultaneously operate the rock-shaft 20 and the bottom pivot 29, the two operating-rods 21 and. 29 are connected to a slid-. ing plate 22, working within a recess near the center of the wing 2. This sliding plate 22 is provided with slots 23, and pins 24. are provided to regulate the movement of said plate.

Said late-22 is also provided with a horiz' on ta-l s' ot 25, which receives a crank-pin 26,

rojecting from a crank-arm formed on or connected to a revolving disk 27, located on the exterior of a face-plate27. 16, and 17.) The revolving disk 27 has a square socket to receive a suitable handle or wrench, and the construction of the parts is such.,that when this disk 27 is given a halfrevolution the rotary motion of the disk through the crank-arm and pin 26 is converted into a reciprocating motion of the sliding plate 22 and its rods21 and 29*. Thus when the )ar ts are in the positions shown in Figs. 17 and 18 the rods 21 and 29 are both in their upper positions,'and hence the pivot 29 is withdrawn from thefloor-socket and the crank-arm 19 is moved u ward, so as to 9 move the locking-arm 13 to t e horizontal or unlocked position. (Shown in Fig.1 1.) It will thus be seen that by the singlemovenient of the revolving disk 27 the Wing 2 may be un-' locked from the hanger or rotating support 11 and at the same time have its bottom pivot withdrawn from the floor-socket, so that this wing 2 is absolutely free from any support at the center.

In order to lock w1ngs' 2 and 4 together, I

employ locking mechanism similar to that (See Figs. 2,

loo

just described and as shown in Figs. 25 to 28,

inclusive Wing 2 is provided with a plate 45, in which the elongated horizontally-disposed slot 50 is located. Win 4 is similarly provided with a late 46, and in an orifice in this plate the s aft 20 turns. This shaft 20* is provided witha locking-arm 13*, which enters the slot 18", and it is adapted to have a quarter-turn against the cam-surface 42 of plate 45, whereby to draw the Wings se- A crank-arm 19 is secured in Figs. 17 and 18 and as previously de scribed. Thus .it is seen that when in use wings 2 and 4 are firmly fastened to each other, as well as to the hanger, and as wing 2 besides being suspended from the hanger or rotating support 11is pivoted to the bottom by means of the pivot 29 and its floor-socket .the wings may be rotated with the utmost ease.

y In addition to the locking means already described wiugs'2 and 4 are each provided with an additional locking means. (Shown in dotted lines in Fig. 1 and designated by the numeral 35.) This locking mechanismis shown more particularly inFigsJ3 to 8, in

elusive, and comprises the'locking-pivots atopposlte ends of the outer extremities of nected to a sliding plate 34, while the other is connected to an arm 34, this plate and arm being pivotally connected together, as shownin Figs. 4 and 6. Projecting from the plate is a crank-pin 36, whose arm 37 rotates with a revolving disk 40, working through the face-plate 41. The construction is such that when a tool is placed within the socket in the revolving plate the parts may be operated to simultaneously move the pivots 35 35 up and down, according to the direction in which the plate 40 is rotated. In other words, when the plate 40 is moved in one di rection the upper pivot 35 is projected upward, while the other pivot 35 is simultahe- 'ously proiected downward, thus locking the outer extremities of the wings 2 and at to the floor and ceiling. ()n the other hand, when the plate il) is rotated .in the opposite direc-' tion the pivots 35 are withdrawn from the ceiling and floor sockets 38, thus releasing the wings, as will be readily understood.

The operation of unshipping and moving aside of the wings is accomplished as follows: Assuming that the parts are in the position shown in Figs. 1 and 2, the latches 31 of Figs. 22. and 24 are first withdrawn, so as to permit the drop-arms 5 to be released and to swing downward. After this is done the wings 1 and 3 may be swung on their hinges, so as to fold against the wings 2 and 4, as shown in dotted lines in Fig. 1. The wings 2 and 4 may now be rotated on the hanger. or rotatable support 11 until the pivots 35 in-the outer cxtremities of said wings come into alinemcnt with the ceiling and floor sockets 38. The faceplate 4-0 is now-rotated to project these pivots 35 into the sockets 38, thus holding the wings from further rotation on the hanger or rotating support. a The operator now uses A the same handle by which the plate 40 was rotated, so as to unlock the wing 4 from the wing 2, and then the same handle may be again used. to operate the plate 27 to withdraw the lower pivot 29 and simultaneously unlock the wing 2 from the. hanger or rotating support 11. T he wing 4 is then unlocked .fIOlll the hanger by operating the lockingarm 13 at the right of Fig. 14 by means of the rod 21. Alter this is done the wings may be swung into the position shown in dotted lines in Fig. 1. It will be manifest that when it is desired to assemble the parts ready for winter use the operation is the re-. verse of that just described.
